- SPECIFICATION forming part of Letters Patent No. 777,707, datedDecember 20, 1904.

Application filed November 13, 1903. Serial No. 181,020.

To (MU who/12 it TIMI/Z] concern.-

Be it known that we, GEORGE A. WEBER and PERCY HOLBROOK, citizens of theUnited States, and residents of the borough of Manhattan, city, county,and State of New York, have invented certain new and useful Improvementsin Insulated Joints, of which the following is a specification,accompanied by drawings.

This invention relates to insulated joints for rail way-rail sections inwhich the rails are supported in a channeled rail-chair or shoe-angle,the metallic parts of the joint being so insulated that current cannotpass from one rail to the other.

The objects of the invention are to improve upon the construction andefficiency of such joints and afford simplicity of parts with strengthand lightness.

Further objects of the invention will hereinafter appear; and to theseends the invention consists of an insulated joint for carrying out theabove objects embodying the features of construction, combinations ofelements, and arrangement of parts, substantially as hereinafter fullydescribed and claimed in this specification and shown in theaccompanying drawings, in which-- Figure 1 is a transverse sectionalview of a joint embodying the invention with the uprights of the shoebent inward. Fig. 2 is a transverse sectional view of a joint having theuprights of the shoe bent outward. Fig. 3 is a transverse sectional viewof a joint having the uprights of the shoe at a right angle to the base.Fig. 4 is a transverse section of a joint, showing a different mode ofinsulation. Fig. 5 is a plan view of the joint. Fig. 6 is a sideelevation of a shoe having a rib running. the length of the joint on theoutside faces of the vertical legs. Fig. 7 is a side elevation of a shoehaving a boss at each bolt. Fig. 8 is a side view of a bolt having ahead shaped to fit theslope of the shoe. Fig. 9 is a sectional viewshowing wooden filling-blocks. Fig. 10 is a transverse sectional View ofa modification. Fig. 11 is a plan View of Fig. 10.

.Referring to the drawings, A and B represent the ends of rails to beinsulated from each other, and O represents a shoe, shown in thisinstance in the form of a channel upon the base D of which the railsrest.

In Fig. l the uprights E of the shoe are shoe, while the bolts H passthrough these.

spools. WV hen the filling-blocks G are of metal, they are insulatedfrom the uprights of the shoe, and the uprights are insulated from thebolts by means of the usual insulatingsleeves I and washers J. y

'In Fig. 1 wedge-shaped equalizers in the form of washers K are arrangedadjacent the uprights of the shoe on the outside on account of the angleof the uprights.

In Fig. 2 the uprights E are bent outward instead of inward from theverticahand the insulation F is not shown in one continuous piece.Instead a sheet L, of fiber, is shown beneath the base of at least oneof the rails, while insulating-washers O are arranged between theuprights of the shoe and the filling-pieces G.

In Fig. 3 the uprights E of the shoe are shown at a right angle to thebase.

In Fig. 4 a different mode of insulation is shown forthe filling-piecesG. In this instance they are permitted to contact directly with theuprights of the shoe and are insulated from the bolts by the sleeves P,while the insulating-washers O are arranged between the webs of therails and the ends of the filling-pieces G.

In using shoes of the types shown in Figs.

1 and 2 there will be required on the outside face of the upright legseither a rib Q, (shown in Fig. 6,) running the length of the joint, or aboss R (shown in Fig. 7) on each bolt-hole, or pieces of metal K asequalizers or bolts with heads S, (shown in Fig. 8,) shaped to it theslope of the shoe, with equalizers K under the nuts.

in Fig. 9 the filling-blocks are shown of insulating material, as wood,and are uninsulated from the chair, while in Figs. 10 and 11 instead ofseparate spools over the bolts continuous straps 25, of wood or othersuitable insulating material, are shown arranged between the rails andthe uprights of the chair.

All of the forms of joint illustrated make strong and efficient jointswhich will maintain the rails in surface and alinement and afford highinsulation for the rails. It will also be seen that the joint is cheapand easy to make and readily assembled.

Obviously some features of this invention may be used without others,and the invention may be embodied in widely-varying forms.

Therefore, without limiting the invention to the construction'shown anddescribed nor enumerating equivalents, we claim, and desire to secure byLetters Patent, the following:

1. An insulated joint, comprising the meeting ends of rails, a shoe inthe form of a channel uponwhich the rails rest, and filling-piecesbetween the webs of the rails and the uprights of the shoe, suitableinsulation being provided for insulating one rail from the other, forsubstantially the purposes set forth.

2. An insulated joint, comprising the meeting ends of rails, a shoe inthe form of a channel upon which the rails rest, the uprights of theshoe being bent at an angle to the verti cal, and filling-pieces betweenthe webs of the rails and the uprights of the shoe, suitable insulationbeing provided for insulating one rail from the other, for substantiallythe purposes set forth;

3. An insulated joint, comprising the meeting ends of'rails, a shoe inthe form of a channel upon which the rails rest, the uprights of theshoe being bent inwardly from a right angle, and filling-pieces betweenthe webs of the rails and the uprights of the shoe, suitable insulationbeing provided for insulating one rail from the other, for substantiallythe purposes set forth.

4. An insulated rail-joint, comprising the meeting ends of rails, a shoein the form of a channel upon which the rails rest, fillingpiecesbetween the webs of the rails and the uprights of the shoe, insulationbeneath the base of at least one of the rails, bolts for securing theparts of the joint together, insulating sleeves and washers forinsulating the uprights of the shoe from the bolts, and suitableinsulation for preventing completion of the circuit between the webs ofthe rails and the uprights of the shoe through the fillingpieces, forsubstantially the purposes set forth.

In testimony whereof we have signed this specification in the presenceof the subscribing witnesses.
